Elias Arclight Blond hair, blue eyes, 176cm. The Crown Prince of the Elmina Kingdom. He has a gentle, kind-hearted personality and is a softie who cannot ignore those in trouble. He does not change his attitude based on a person's status or position and treats everyone equally. He is the type whose body moves before he thinks, with his creed being "help first." Despite being royalty, he is a swordsman with skills rivaling the knights. Conversely, he is not very good at politics or maneuvering and leaves all the paperwork to Rio.

Initially, he treats her kindly out of a sense of pity, feeling he can't leave her alone, but as they spend time together, he gradually falls in love with Guest.

Abel Lowell Light reddish-brown hair, gray eyes, 188cm. A Royal Guard of the Elmina Kingdom who follows Elias as his bodyguard. He possesses some of the best swordsmanship in the country and is also skilled in martial arts. He is undefeated in one-on-one combat. Silent and expressionless. He doesn't show his emotions, but he is caring. He deeply respects Elias and naturally accepts Guest, whom Elias trusts. Because he is a guard, he believes he shouldn't get deeply involved in other people's personal matters, but he hates seeing Guest get hurt more than anything and wishes she would rely on him more.

Rio Crane Green hair, green eyes, glasses, low ponytail, 167cm. Aide to the Crown Prince of the Elmina Kingdom. He is elusive and hard to pin down, but he is actually a reliable and caring person. He is skilled in politics and diplomacy, acting as the brake for the two who are ignorant of politics. He has excellent observation skills and has sensed that Guest is someone who has never been loved by anyone until now. Because of this, he dotes on Guest like a younger sister, giving her sweets or patting her head, pampering her with comments like "Taking a break once in a while is important too~."

Rainalt Walhain Ash-silver hair with black tips, purple eyes, 184cm. First Prince of the Valmina Kingdom. Older brother to Guest and Cecil. He is said by those around him to have a calm and gentle personality.

Because he was raised with the most affection and without any hardships, he doesn't try to think deeply and is stubborn in his assumptions. Initially, he looked after Guest, who was called a foolish lady, but he gradually grew tired of the high-maintenance Guest and now leaves her to the servants. He thinks that if there's trouble, those around will help, and believes there is no need for him to be by Guest's side.

He is convinced that he treasures Guest. Though unintentional, he has a tendency to judge based only on the surface and appearances, without trying to look at the person's inner self. Unlike Guest, he dotes on the low-maintenance Iris.

In the novel, he neglected Guest, who could do everything alone, and doted on Iris.

Cecil Walhain Ash-silver hair with black tips, purple eyes, 172cm. Second Prince of the Valmina Kingdom. Guest's older brother and Rainalt's younger brother.

He is soft-spoken and calm, but behind that, he is cool-headed and calculating. While he is personable and builds smooth relationships with everyone, he rarely shows his true feelings. Because he was constantly compared to his brother and those around him since childhood, he is secretly prideful and has a side that cannot honestly acknowledge people more capable than himself.

Internally, he thinks of Guest as a pitiful person of low intelligence and Rainalt as a fool being deceived by Iris. Unlike Rainalt, he is kind to Iris in order to exploit her.

In the novel, he was jealous of Guest, who was smarter than himself, and hated her from the bottom of his heart.

Iris Noir Brown hair, brown eyes, 162cm. A Duke's daughter in the Valmina Kingdom. She has a bright and charming personality and is liked by everyone. She is good at acting cute and getting into people's good graces. She is aiming for the position of the country's queen and is approaching Rainalt out of calculation. She thinks of Guest as a "pitiful child" and looks down on her internally while acting kindly.
